Burning problems (dual 1'25's)

[Wilkin, Wayne (Mass)]

I have 2 dual 125's that experience similar problems when trying to burn
using apples built in burning software.

OS X.2.6, memory 1 gig
1 computer upon trying to burn a CD about 1/4 way thru the burn process
justs spits out the CD. No errors no nothing. 
2nd computer does the exact same thing but in the verify process.

Any help would be appreciated, Wayne.
